void GDALDriverManager::AutoLoadDrivers

(

)

static

Auto-load GDAL drivers from shared libraries.

This function will automatically load drivers from shared libraries. It searches the "driver path" for .so (or .dll) files that start with the prefix "gdal_X.so". It then tries to load them and then tries to call a function within them called GDALRegister_X() where the 'X' is the same as the remainder of the shared library basename ('X' is case sensitive), or failing that to call GDALRegisterMe().

There are a few rules for the driver path. If the GDAL_DRIVER_PATH environment variable it set, it is taken to be a list of directories to search separated by colons on UNIX, or semi-colons on Windows. Otherwise the /usr/local/lib/gdalplugins directory, and (if known) the lib/gdalplugins subdirectory of the gdal home directory are searched on UNIX and \gdalplugins on Windows.

Auto loading can be completely disabled by setting the GDAL_DRIVER_PATH config option to "disable".

void GDALDriverManager::AutoSkipDrivers

(

)

This method unload undesirable drivers.

All drivers specified in the comma delimited list in the GDAL_SKIP environment variable) will be deregistered and destroyed. This method should normally be called after registration of standard drivers to allow the user a way of unloading undesired drivers. The GDALAllRegister() function already invokes AutoSkipDrivers() at the end, so if that functions is called, it should not be necessary to call this method from application code.

Note: space separator is also accepted for backward compatibility, but some vector formats have spaces in their names, so it is encouraged to use comma to avoid issues.

Normally this method is used by format specific C callable registration entry points such as GDALRegister_GTiff() rather than being called directly by application level code.

If this driver (based on the object pointer, not short name) is already registered, then no change is made, and the index of the existing driver is returned. Otherwise the driver list is extended, and the new driver is added at the end.

Parameters

poDriver

the driver to register.

Returns

the index of the new installed driver.
